The mixed ratio of cold and hot water can be regulated by way of a manual operation to regulate the outlet water temperature. The deficiencies of this method lie in: on one hand regulating accuracy is insufficient; on the other hand, when the inlet water temperature varies, the manual regulation should be carried out increasingly to ensure the outlet water temperature approaching a setting value. Furthermore, a number of the automatically mixed regulating valves generally regulate the mixed ratio of cold and hot water by way of bimetallic elements, memory metals or liquid expansion structures which are not only working as sensing elements, but also as executive elements so as to result many problems of an inconvenient regulation, a slow response, an insufficient regulation accuracy. Furthermore, since the predetermined temperature of the valve body cannot be varied by the quantity of electricity, it is rather difficult as for this kind of mixed regulating valves to perform an automatic control in collaboration with its peripheral units and to guarantee a long term stable work and a longer service life.
